DECATUR --- A 28-year-old woman driver was charged with driving under the influence Wednesday morning after her SUV collided with an ambulance in a wreck that injured four people, according to Decatur police.

Paula Campbell, driver of the GMC Yukon, was charged with DUI after being treated and released from Decatur General Hospital, Decatur police spokesman Sgt. John Crouch said. Christine Brooker, 32, a passenger in the Yukon, was airlifted by Med Flight to Huntsville Hospital with life-threatening injuries, he said.

Will Nessman, the driver of the Decatur Emergency Service ambulance, was taken to Decatur General with non-serious injuries and EMT Cassey Rutherford was transported with non-life threatening injuries, Crouch said. She underwent surgery and her condition is unknown, he said.

The crash happened about 7 o'clock Wednesday morning near Ingalls Harbor on Alabama 20. According to Crouch, the Yukon attempted to turn onto Neher Road, an entrance to the harbor, in front of the ambulance. The ambulance was unable to stop and struck the Yukon in the passenger side, flipping the Yukon onto its side, Crouch said.

Additional charges may be filed against Campbell at the conclusion of the accident investigation.
